Variation sequences

The Supplemental Mathematical Operators block has eight variation sequences defined for standardized variants. [3] [4] They use U+FE00 VARIATION SELECTOR-1 (VS01) to denote variant symbols (depending on the font):

U+2A3D RIGHTHAND INTERIOR PRODUCT⨽⨽︀tall variant with narrow foot

Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF.

Letterlike Symbols is a Unicode block containing 80 characters which are constructed mainly from the glyphs of one or more letters. In addition to this block, Unicode includes full styled mathematical alphabets, although Unicode does not explicitly categorize these characters as being "letterlike."

Miscellaneous Technical is a Unicode block ranging from U+2300 to U+23FF, which contains various common symbols which are related to and used in the various technical, programming language, and academic professions. For example:

Supplemental Arrows-B is a Unicode block containing miscellaneous arrows, arrow tails, crossing arrows used in knot descriptions, curved arrows, and harpoons.

Miscellaneous Symbols and Arrows is a Unicode block containing arrows and geometric shapes with various fills, astrological symbols, technical symbols, intonation marks, and others.

Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.

The Basic Latin Unicode block, sometimes informally called C0 Controls and Basic Latin, is the first block of the Unicode standard, and the only block which is encoded in one byte in UTF-8. The block contains all the letters and control codes of the ASCII encoding. It ranges from U+0000 to U+007F, contains 128 characters and includes the C0 controls, ASCII punctuation and symbols, ASCII digits, both the uppercase and lowercase of the English alphabet and a control character.

The Latin-1 Supplement is the second Unicode block in the Unicode standard. It encodes the upper range of ISO 8859-1: 80 (U+0080) - FF (U+00FF). C1 Controls (0080–009F) are not graphic. This block ranges from U+0080 to U+00FF, contains 128 characters and includes the C1 controls, Latin-1 punctuation and symbols, 30 pairs of majuscule and minuscule accented Latin characters and 2 mathematical operators.

CJK Symbols and Punctuation is a Unicode block containing symbols and punctuation used for writing the Chinese, Japanese and Korean languages. It also contains one Chinese character.

Mongolian is a Unicode block containing characters for dialects of Mongolian, Manchu, and Sibe languages. It is traditionally written in vertical lines Top-Down, right across the page, although the Unicode code charts cite the characters rotated to horizontal orientation as this is the orientation of glyphs in a font that supports layout in vertical orientation.

Myanmar Extended-A is a Unicode block containing Myanmar characters for writing the Khamti Shan and Aiton languages.

A variant form is an alternate glyph for a character, encoded in Unicode through the mechanism of variation sequences: sequences in Unicode that consist of a base character followed by a variation selector character.

Variation Selectors Supplement is a Unicode block containing additional variation selectors beyond those found in the Variation Selectors block.

Phags-pa is a Unicode block containing characters from the 'Phags-pa script promulgated as a national script by Kublai Khan, the founder of the Yuan dynasty. It was used primarily in writing Mongolian and Chinese, although it was intended for the use of all written languages of the Mongol Empire.

General Punctuation is a Unicode block containing punctuation, spacing, and formatting characters for use with all scripts and writing systems. Included are the defined-width spaces, joining formats, directional formats, smart quotes, archaic and novel punctuation such as the interrobang, and invisible mathematical operators.

Dingbats is a Unicode block containing dingbats. Most of its characters were taken from Zapf Dingbats; it was the Unicode block to have imported characters from a specific typeface; Unicode later adopted a policy that excluded symbols with "no demonstrated need or strong desire to exchange in plain text", and thus no further dingbat typefaces were encoded until Webdings and Wingdings were encoded in Version 7.0. Some ornaments are also an emoji, having optional presentation variants.

Arrows is a Unicode block containing line, curve, and semicircle symbols terminating in barbs or arrows.

Halfwidth and Fullwidth Forms is the name of a Unicode block U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to/from Unicode. It is the second-to-last block of the Basic Multilingual Plane, followed only by the short Specials block at U+FFF0–FFFF. Its block name in Unicode 1.0 was Halfwidth and Fullwidth Variants.

Variation Selectors is a Unicode block containing 16 variation selectors used to specify a glyph variant for a preceding character. They are currently used to specify standardized variation sequences for mathematical symbols, emoji symbols, 'Phags-pa letters, and CJK unified ideographs corresponding to CJK compatibility ideographs. At present only standardized variation sequences with VS1, VS2, VS3, VS15 and VS16 have been defined; VS15 and VS16 are reserved to request that a character should be displayed as text or as an emoji respectively.

Manichaean is a Unicode block containing characters historically used for writing Sogdian, Parthian, and the dialects of Fars.
